My favorite part of reading The Strain was the yuck factor. These vampires are disgusting — pieces of their body fall off and they leave trails of feces behind them. Needless to say, I'm excited to see how the TV series will handle it — but these two featurettes are quite promising.

These two new featurettes on The Strain series perfectly bookend the two reasons we're excited about this series — for the vile biological horror and for the supernatural backstory. One video describes the world in which a real vampire race exists, and the other sets up the elaborate supernatural backstory. And if GDT and Carlton Cuse's new TV series can continue to straddle both the magical and the medical, then The Strain could be pretty great. But for now, all we have are these previews, so enjoy.
